Description of absoluteBLACK Chainring - Direct Mount - Narrow Wide - Oval for XTR M9100/M9120 - grey

The Original one and only absoluteBLACK Premium, Shimano XTR M9100 compatible Direct mount 1X Oval traction chainrings are designed for Shimano XTR M9100 and M9120 cranks Only. They feature exactly the same excellent oval shape as rest of our oval chainring portfolio. This new type of direct mount chainring will make your Shimano crank looking great. This particular chainring will ONLY work with CN-M9100 chain due to different thickness of the teeth.

Fits only Shimano XTR M9100 and M9120 cranksets.

Oval (elliptical) chainrings work because a rider does not produce power evenly through a pedal stroke; they maximize the part of the stroke where power is produced and minimize resistance where it isn't. Oval rings make the spin cycle a lot smoother and are easier on legs while climbing. Believe it (or not), but a round chainring doesn't transfer torque to your rear wheel as smoothly as an Oval one. You will actually feel your stroke to be more "round" with an Oval shape than with a round chainring.

It's a Direct Mount chainring so please use original lockring to mount it on the crank. Always use a new chain with a new chainring.
If you wish to check for frame clearance with new oval ring, below you can find measurement of biggest dimension of the oval (tip to tip of tooth): 28T: 127mm ; 30T: 134mm ; 32T: 143mm ; 34T: 151mm
Chain options: 10, 11 or 12spd chain for geared bike or 6-9 spd one for SS (1/8" also fits).

How to mount Absoluteblack oval chainring for XTR M9100:
Using Hollowtech II BB Removal Tool (like BBB BTL-116 ), carefully open the lockring that holds the chainring on the crank(normal threads). Once the lockring is removed, take off old chainring, re-grease the splines on the crank. Place new oval chainring with convex side to the crank. Chainring/crank has special splines that only fit one way. Close the lockring to 35-50Nm of force. Chainring is only compatible with XTR CN-M9100 chains. Using other chains may cause chain to drop very easily from the chainring due to thinner than usual teeth.

Ovality of the chainring is in range of 10-14% (dependent on size) and feels perfectly round when riding. These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting. It is the most advanced oval chainring currently on the market.
